Grid Shake-Up: Reactors Return

After decades of experts saying America couldn’t build new nuclear reactors, two advanced plants are now under construction on U.S. soil — and they are aimed straight at powering our energy-hungry, AI-driven future.

Story Snapshot

TerraPower and Kairos Power have moved from talk to shovels in the ground, breaking a long nuclear construction drought.
Federal policy and Trump-era energy priorities are pushing nuclear as a way to cut costs, secure the grid, and fight past “green” failures.
Big Tech’s push to power AI with reliable nuclear energy risks new forms of government favoritism and community-level safety worries.
Real cost, fuel, and supply-chain problems mean these projects are a major step, not a finished win — yet.

America Is Building Advanced Reactors Again

TerraPower’s Natrium reactor in Kemmerer, Wyoming is now under construction, making it the first advanced non-light-water nuclear project to move from design to building in the United States. The plant is a 345-megawatt sodium-cooled fast reactor that can boost output to about 500 megawatts with a molten salt energy storage system, enough to power roughly 400,000 homes when needed. It sits next to a retiring coal plant, turning a symbol of past American energy strength into a new hub for reliable, carbon-free power.

The U.S. Nuclear Regulatory Commission (NRC) issued a construction permit for Kemmerer Unit 1 in March 2026, the first such permit for a non-light-water reactor in half a century. TerraPower’s CEO said the company is “objectively” the next commercial nuclear station set to come online in America, underscoring how rare it is to see a brand-new reactor approved and moving forward. Bechtel, a major U.S. engineering firm, has joined the project and is now mobilizing crews on site, with full construction expected to take about five years.

Big Tech Bets Billions On Nuclear-Powered AI

TerraPower’s project is not just about grid power; it is part of a larger push by technology giants to lock in long-term electricity for artificial intelligence and data centers. The federal government has approved up to $2 billion in funding under the Advanced Reactor Demonstration Program, using a fifty-fifty public–private cost share to back the Natrium plant as a commercial-size demonstration. Meta Platforms has announced funding to accelerate up to eight additional TerraPower units, signaling that Silicon Valley wants nuclear energy, not just wind and solar, to feed its servers.

Kairos Power is following a similar path with its Hermes 2 reactor in Oak Ridge, Tennessee, built on the site of the former K-33 uranium enrichment plant. Hermes 2 is designed as a commercial-scale reactor of about 50 megawatts, with a deal to send power to the Tennessee Valley Authority grid and support Google data centers. Under that agreement, Kairos and Google are working toward a fleet of reactors that could deliver 500 megawatts by 2035, showing how private tech money is now a core driver of U.S. nuclear construction.

Trump-Era Policy Shifts Push Nuclear Forward

Recent federal policy changes have made this nuclear comeback possible, including bipartisan reforms but also Trump-era moves that put American energy dominance back at the center of national strategy. The Department of Energy created a fast-track reactor pilot program so some advanced designs can reach “criticality” at non-federal sites as early as July 4, 2026, bypassing parts of the old licensing maze for initial testing. The NRC was directed to provide more predictable, timely reviews for reactors built at retired coal and fossil-fuel sites, cutting years of delay by using existing grid connections instead of starting from scratch.

These steps reflect frustration with decades of environmental red tape, anti-nuclear activism, and climate “solutions” that raised electric bills while failing to secure the grid. For many conservatives, seeing new reactors on the ground is proof that when Washington supports energy projects instead of blocking them, American engineering can still deliver. At the same time, some watchdogs warn that fast-track tools and narrower environmental hearings could leave nearby residents feeling shut out of safety debates.

The Hard Truth: Costs, Fuel, And Foreign Pressure Still Loom

Even with these wins, the nuclear industry’s history of huge cost overruns and delays has not disappeared, and critics point to recent projects as warnings. The Vogtle expansion in Georgia took roughly sixteen years and cost about $35 billion, becoming a symbol of how nuclear build-outs can spiral when regulations and supply chains get messy. No small modular reactor has yet finished construction and entered commercial service in the West; NuScale’s Idaho project was canceled in 2023 after costs climbed and customers walked away. For now, America’s “advanced reactor revival” is real in steel and concrete, but not yet proven in long-term operations and power bills.

Fuel and materials are another serious challenge, especially for advanced designs that rely on high-assay low-enriched uranium produced at only a handful of U.S. facilities. Russia once supplied a large share of American enrichment, but a 2024 ban on Russian imports has forced a scramble to build domestic capacity, which will take years and heavy investment. China’s control of most global refined silver and its 2026 export restrictions highlight how foreign rivals can choke key inputs for reactors, grids, and AI hardware, putting America’s energy independence and national security back on the line.

What This Means For Conservative Readers

For right-of-center Americans, these two reactors are a turning point: evidence that the country can still build big, hard infrastructure when government finally gets out of the way and backs real projects. Nuclear power offers dense, reliable energy that does not depend on the weather, supports heavy industry, and can lower long-run costs compared with endless subsidies for intermittent sources. But the same forces that stalled nuclear before—bloated regulation, activist lawsuits, supply-chain dependence on hostile nations, and elite bias against baseload power—are still active and looking for chances to slow or reshape this revival.

Success will depend on keeping licensing honest but efficient, protecting local communities without handing veto power to radical green groups, and demanding transparent cost and safety data from both companies and federal agencies. If TerraPower and Kairos deliver on time and on budget, America could regain nuclear leadership, secure energy for AI and manufacturing, and prove that talk of national decline was wrong. If they fail, it will be used as ammo by those who want more government control, more fragile grids, and fewer choices for families and businesses.
